Abstract Recently, the coexistence of a parity‐time (PT) symmetric laser and absorber has gained tremendous research attention. While PT‐symmetric lasers have been observed in microring resonators, experimental demonstration stripe is still absent. Here, we experimentally study waveguide. Using concept PT‐symmetry to exploit light amplification absorption, absorbers successfully obtained. In contrast single‐mode lasers, confirmed by comparing relative wavelength positions mode spacing under...
Recently, the coexistence of parity-time (PT) symmetric laser and absorber has gained tremendous research attention. While PT been observed in microwave metamaterials, experimental demonstration is still absent. Here we experimentally study PT-symmetric stripe waveguide. Using concept symmetry to exploit light amplification absorption, absorbers have successfully obtained. Different from single-mode lasers, lasers confirmed by comparing relative wavelength positions mode spacing under...
Non-Hermitian systems exhibiting topological properties are attracting growing interest. In this work, we propose an algorithm for solving the ground state of a non-Hermitian system in matrix product (MPS) formalism based on companion Hermitian Hamiltonian. If eigenvalues known, Hamiltonian can be directly constructed and solved using variational methods. When unknown, gradient descent along with yields both eigenenergy eigenstate. With principle as solid foundation, our ensures convergence...
